To all whom it may concern:

Be it known that I, RAY J. LYMAN, a citiresiding at Berkeley, 1n the county of Alameda and State of California, have invented certain new, and useful Improvements in Liquid-Measuring Devices; and I do declare the followirig to be a full, clear,

invention, such as will enable others skilled in the art 'to which it appertains to make anduse the same.

This invention relates to certain new and useful improvements in liquid measuring devices. v

One object of the invention'is to provide mean for automatically registering a quantitv of liquid which' is same, and is particularly applicable in conamount of gasoline introduced into the tank of an automobile.

Another object of the invention is to provide a registering device of this character in which the registering mechanism is automatically locked when no fluid is" passing through the device.

.A furthei" object of the inyent ion is' to.

. improve upon devices of this general nature by the provision of a comparatively simple,

strong, durable and inexpensive construction, one which willbe efficient and reliable in operation, and well adapted to the purpose for'which itis designed. I

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arparts as will be here1nafter' rangement of fully described and claimed.

and in this connection'the numeral 1 designates a casing of cylindrical shape provided.

wit -a curved circular flange 2 at its lower side to facilitate in attaching the casing to {he filling opening a of the automobile gasome a horizontally disposed partition 3 dividing the same into an upper chamber 4 and a lower chamber 5. These two chambers communicate with each other by: means of a curved by-pass 6, and the upper chamber 4:-

1s provlded with a filling opening or inlet 7 normally closed by a screw cap 8, while the provided with. a'centrally disposed outlet 9. The lower chamber 5 is also provided with an annular channel 10, the latter surrounding-the outlet 9 and overflowing intothe same. The aforementioned bypass 6 enters the .chamber 5 at a point adjacent the well 10, so that liquid enters; the latter from a tangential direction.

Arranged in the upper side of the casing '1 and in the partition 3 and disposed in alinement centrally of the casing is a pair of bearings in and 12, and in these bearings is mounted 'a shaft 13, the latter being disposed vertically and having outwardly extend ng and downwardly inclining arms 14: at its lower ends. Carried at; the lower ends of the arms 14 are blades or paddles 15 which tank 6. The casing 1 is provided with.

dip into the channel 10 so that they will propel the shaft 13 when through said channel.

The upper end of the shaft 13 is provided with aiworm 16 which m'esheswith a worm wheel 17, the latterbeing cdnnectcd with-a suitable indicator 18 in such a manner that when the shaft 13 revolves the indicator; wlll be actuated.- This. indicator 18 is here shown arranged in a suitable; cover and 1s disposed at the upper side of the casing 1.

liquid is passing The outlet '9 is provided witha downwardly opening self closing valve. 19, this self closing feature being accomplished bya-spring 2O surroundingthe valve rod 21 and disposed between a stop 22 carried by from "the inner wal of the well 10.; When the valve is closed the rod 21'extends up far enough to be. disposed in the path of'the arms 14 and this serves to lock the turbine 23 projecting inwardly (the shaft 13, the arms 14 and the blades-15) against rotation to such an extent as to change the readin of the register.

In operation, w enthe cap 8 is removedchamber 5 it will flow into and around the channel striking the blades from a tan- ,gential direction and causing the turbine to rotate and operate the register 18. From the channel 10 the gasoline will overflow into 10 the outlet 9 and its weight opens the valve "19 so that the rod 21 is moved out of the pathot' the arms 14. The motion of the turbine contlnues as long as gasoline is being poured into theinlet 7 andthe valve 19 is held open by the gasoline passingthrough the same on its way to the tank.

From the foregoing description taken 1n connection with the accompanying drawings the construction, use and operation of the invention will be readily understood.

As various changes in form, proportion, and in the minor details of construction may. be resorted to without departing from the spirit of this invention it is to be understood 25 that I do, not wish to be limited to theprecise construction herein shown and described.

Iclaim: v 1. A device of the class described comprising a casingv having an annular channel 1n at its lower end, an inlet leading into said channel, an outlet from the casing formed by the inner wall of said channel, a turbine mounted in said casing and having blades dipping into said channel to be rotated by the liquid sfi'flowing therethrough, and a register operatively connected with said turbine.

2. A device of the class described comprising a circular casingv having a tangential inlet in its vertical wall and having a central 4o outlet in its bottom surrounded by an annular channel, the rim .of said outlet being above the bottom of the .channel, a vertical shaft rotatably mounted in said casing in axial alignment with. said outlet, arms de 435 pendmg from said shaft and having paddles operating in said channel, and a register operatlvely connected with said shaft.

3. A device of the class described com prising a casing having a horizontal partition dividing it into an upper chamber and a lower chamber, said upper chamber hav: ing an inlet while the lower chamber is provided with an outlet, a by pass around the partition establishing communication between said chambers and opening tangentially into the lower chamber, a turbine mounted in said lower chamber, and a register operatively connected with said turbine.

4. A device of the class described comprising a casing divided by a horizontal partition into an upper and a lower chamber, said upper chamber having aninle't while the lower portion of the lower chamber is provided with an outlet bordered by an up standing flange providing an annular channel between itself and the casing wall, a by pass around said partition placing said "upper and lower chambers in communication and opening tangentially into the lower chamber, a turbine rotatably mounted in said casing and having paddles operating in said annular channel, and a register operatively connected with said turbine.

5. A- device of the class described comprising a casing having an inlet and an outlet, a turbine mounted in said casing, a register operatively connected with said turbine, and liquid-released means at said outlet for normally holding said turbine against operation, but for releasing said turbine for use when liquid is passing through the casa 6 A device of the class described comprising a casing having an inlet and an outlet, a turbine mounted in said casing, a register operatively connected with said turbine, a self-closlng outwardly-opening valve mounted in said outlet, and means carried by said valve for locking" said turbine against operation only when said valve is closed.

In testimony whereof I have hereunto set my hand.
